Jack looked at kurama and was surprised that he would agree. What he didn't know was that although kurama didn't have much hope towards this treatment, but after knowing that this guy kept going from a 12 year child struggling with a chronic illness and still have such pure heart without any malice, he said to himself why not.
Not to mention that they really need to do something if they want to try to change the end of the ninja world.
Jack said
"well let's start."
He began with simple question like
"What is the first thing you remember "
And then kept digging deeper with difficult questions like
"What physical sensations arise with this feeling? Where do I feel it in my body?"
Or
"What would 'letting go' of a fraction of this feeling look like today? What space might that create?"
Kurama was of course uncooperative patients by any meaning. He would get angry, quiet then furious then laughing. He was like a tight close can of emotions that would burst from time to time.
The treatment kept going for three years.
During these Jack would talk about his world from novels to movies to comics.
They shared everything thing during their time together and finally kurama let go of his hatred after three years of comprehensive therapy.
At his final session kurama said with moisty eyes
"Thank you."
"You are welcome. Now are you sure we can bump first together."
"Yeah, I'm ready."
They extend their first to each other and bumped it together, the moment that happened, they connected internally and their thoughts connected.
This kept going for a while until kurama looked up in surprise.
Jack was taken back by kurama surprise and asked.
"Is there something wrong."
"....I just figured out why you are here, your soul, I think it has a lot of similarities with naruto. That's maybe why you are in here."
Jack was taken back and then asked.
"Did my soul maybe change because I have living inside his body for so long."
"Hahahaha, no . Your soul didn't change. Even though I just noticed your similarities with naruto, I know for a fact that your soul didn't change. It became more powerful of course because you were influenced by being next to me for years making your current soul power more impressive than anyone I have met before but that doesn't mean it changed"
Jack of course knew about his soul powering up as he kept next to kurama for years suffering from outbursts here and there during their sessions leading to his increase of soul power.
Jack felt relief that it doesn't seem he would assimilate with naruto. Because he saw this as murder to a young child.
Jack then felt chakra latching on him and felt this new profound power but didn't feel any discomfort.
"Looks like you succeeded, kurama "
"Hahahaha, of course."
Kurama was really happy. He felt that a huge burden was relieved and that he was as light as a feather.
Jack was also happy for him . Then he said.
"Good. Now , I will try removing the seal and waking up the fourth hokage. But as he might attack, remember to yell at him when he shows up as a form of distraction so that I can escape inside the cage."
"Hehehe, don't worry he would be shaking from shock when he feels that someone is trying to remove the seal."
"No , I wouldn't. "
Jack and kurama jumped in surprised as they heard a new voice suddenly appearing.
They turned to the place where the voice came from and saw the fourth hokage standing there with a sunny smile on his face.
Jack was so shocked that he didn't know what to say or do while kurama yelled.
"Yondime , how long have you been awake."
kurama felt nervous about what the fourth hokage heard and if he knew about their therapy sessions.
"I was awake from the start. I never meant to eavesdrop on your sessions but I couldn't speak without undoing the sealing and knowing that I couldn't keep my chakra for a long time, I couldn't undo the sealing"
"You bastard , how dare you spy on our conversation the whole time "
Kurama was furious about his inner secrets leaked to his what consider to be a former enemy .
"I'm sorry, there are no excuses , even though I could stop listening to your sessions, I didn't as you both might harm naruto, my son , if anything goes wrong."
Jack at first was also slightly apprehensive about Minato spying on them but when he heard that, he put himself on his shoes and nodded that he would absolutely do that.
It's my child life that you are talking about, there's no way I would leave the two people inside my son without paying attention to them.
Kurama however was still furious. He shared a lot of embarrassing things with Jack and it was because he didn't need to worry about anything getting leaked but this form of invading his privacy was infuriating.
Jack however understanding said.
"Okay, although I also feel apprehensive, It's understandable. So I forgive you."
Kurama who seething with anger looked at Jack with surprise. Even though kurama shared with Jack a lot of embarrassing things, Jack also talked a lot about private things but he forgave him so quickly.
"Thank you, although it's still wrong and a lot late but my condolences . I heard about your death and I'm sorry."
"Well, you also have my condolences . But there's no need, I'm over it."
Minato looked at Jack and kurama and then said.
" as you know while listening to your conversation, I also tried to come up with a solution, And the only the thing that came to my minds is Spirit Transformation Techniques.
This technique allows a person to become a living spirit in order to attack his opponents. He can also use it to take control of a target's body.
I know of the technique but I didn't learn and now I'm only a chakra remnant not a soul, so Jack, only you can use this technique. But what will you do after learning it . Would you go the Uchiha compound and try to warn them? . That doesn't seem to be a good idea."
Jack thought for a while and then said
"well, before we do anything, can you bump fist with kurama so as to know that you aren't harboring any scheme towards us."
Minato was surprised as he thought that Jack was somewhat naive and easy to trust others but that doesn't seem to be the case. Is it because he had been spying on there conversation and still have some issues with the matter?.
Jack saw that Minato looked surprised and said
"No, it's not because you have been listening to our conversation in secret. It's more of a reassurance as I know you could have changed your future but you refused and sealed your memories as you were thinking that changing future might lead to a catastrophic events."
Minato frowned looking at Jack with a puzzled look.
Jack said
"In one of naruto missions he happened to meet the past you while you were still a jonin but when you knew about them coming from the future, you sealed all the people memories included in the mission."
Minato was surprised again but he felt that might be something he would do.
"Okay, I understand."
Saying that he bumped fist with kurama and after a while they retracted their fist but not without kurama sharing some of his chakra with Minato.
Minato felt that with this chakra he could continue to exist for years and he said.
"Thank you, kurama "
Kurama didn't respond and just hmphed.
After that kurama turned to Jack and nodded.
Jack smiled saying.
"Great, now we can start. Although I don't if I can do it but I think I need to start from the basics."
Minato was surprised but then thought about and nodded in understanding. As you can't start teaching a novice an S- Rank ninjutsu at the start.
And so two weeks passed, during which naruto got kicked out of the orphanage and was living alone now.
Kurama being kurama took a slight pleasure to Minato discomfort as his former enemy so he teased him about what Konoha upper echelons doing to Minato child.
"Hehehe, Minato looks like the third hokage wants to isolate naruto so that he can appear in front of him as hero. Well, you would know as you also was brainwashed by the will of fire. By the way don't you think you should wake up kushina. I think she should love watching Naruto growing up."
Minato face was looking like he ate shit before kurama spoke and now he knows that he really needs to wake kushina as she wouldn't forgive him if she knew that could have woken up earlier but Minato didn't do it.
Sighing about what about to happen, he formed a number of seals and then kushina appeared with somewhat puzzled face.
"Minato, what's going on, why would you suddenly woke me up. Did the kyubi start to rampage and you can't seal him?"
Kushina was air headed, that's the conclusion that Jack could think of as she spoke to Minato without even turning her head .
"Oh kushina, long time no see. Seeing your tomato hair brings back some shity memories"
Kurama said while taking a pleasure in the couple plight as they will witness the discrimination against their son from the whole village they died to protect.
But kushina reaction was beyond kurama expectation as chains suddenly spread from her body and started to strangle him.
"Kyubi, are trying to swallow Naruto and destroy Konoha , I won't allow you "
"Wait kushina, that's not it. Calm down first. This isn't something related to kurama."
Kushina looked at Minato for a while and then retracted her chains and then said.
"Minato, what's going.it's doesn't seem like Naruto is in danger so why did you wake me up. You know that our time is limited."
"Well, first of all I would like to introduce you to someone. This is Jack. Jack I assume you know kushina my wife."
Jack was looking at kushina and kushina turned her head then saw Jack and was flabbergasted.
Jack said
"Hello, I'm Jack , big fan by the way."
Kushina was one of the favorite characters of Naruto for everyone . While Minato was was also a favorable character but Kushina was much better. Her death scene was so tearful and painful for many people. This pure person in this fuck up world was something fresh and when naruto meets here was also a memorable moment.
Kushina was still surprised by this new face but responded with confused face.
"Hello, nice to meet you. But what do you mean by big fan."
Jack responded
" your character was one of the favorite characters in the series. Many people cried for injustice when they saw your death scene. It really was tear jerking".
Kushina was more confused so Minato took her to the side and then began to explain everything about Jack and what happened in the last three years.
Meanwhile Jack came to kurama and said to him.
"Kurama, while I know you like to tease Minato and I don't really mind but kushina is a different matter. Minato Might be able to understand what the know upper echelons is doing but kushina is his mother and nothing more painful than seeing your own child live in isolation. So please I'm asking you as a favor not to tease about naruto as it will be a hundred times more painful to her than when you pierced through them with your claw.and remember kushina doesn't have many good memories of Konoha so it wouldn't be a good idea to tease her"
Kurama was taken back but when he looked at kushina and remembered his time with her, although it wasn't a good time, at least she didn't seem to mind but she was innocent and was only looking at him through a colored glass tainted by those around her.
After thinking about for a while he decided that he would have to wait to see her reaction first.
He then suddenly heard kushina saying with excitement .
"Really, we can keep seeing naruto growing up and our chakra wouldn't be depleted."
Kurama heard her excited voice and knew that couldn't bring himself to say anything about naruto.
So he felt bored and stared to watch movies from Jack's world.
It became his favorite hobby to watch movies.
Suddenly kushina came to him and said
"Thank you, kurama without you, I wouldn't get the chance to see naruto growing up. You too Jack , thank you for getting rid of the hatred in kurama heart, thank you, thank you"
Kushina said with tears in her eyes. But this tearful scene made the three people feel like a gut wrenching pain instead of it being a beautiful moment.
They felt that way because they know how naruto is treated in the village and how the upper echelons planned a plot to isolate him and being discriminated against him.
Kushina saw that they didn't respond to her thanks and thought they were embarrassed. So she just skipped over the matter and didn't embarrass them. Kurama then shared some chakra with her and she began to watch Naruto outside.
Meanwhile Jack was progressing in his training.
During these two weeks he began learning from the basics and as he doesn't have a chakra of his own to test what type is it.
So he focused on non attribution chakra practice. Jack was a genius that he progressed so fast and Minato was surprised by how fast his growth.
He learned the academy technique in the first week. That sounds like a lot of time for a fast growth genius .
Well , the reason for that was because the normal way of practice didn't apply to Jack as he didn't have any of the entire network of chakra pathways (tenketsu) running throughout the body, or the 361 main chakra points (tenketsu points) where these pathways converge near the surface.
So what he did was is a combination from the knowledge from his previous life about Chinese medicine and Minato teaching about the techniques to execute them.
After that he practiced chakra control and body flicker technique. Finally the signature technique of the fourth hokage, Rasengan .
